Thanks for the reply's. I have an infra-red thermometer gun that I have been measuring my soil temps with and on top of the soil they are averaging 75Ëš to 80Ëš. On the very bottom of the seed tray they are between 95Ëš to 100Ëš.
If I measure directly in the middle of the seedling cell it averages 83Ëš to 87Ëš. Since where the seeds are planted I would say they are in the 80Ëš to 85Ëš range of the soil temp but I was trying to understand where most people measure their soil temp.
Also, to maintain those temps there is no way I can leave the domes on the trays because it gets too hot. Trying to decide if I should get the thermostat so I can leave the dome on and maintain the same temperature.
Suggestions?
